the womans place in the society as the determining factor for success/greatness
the environment..ability to cultivate the land and be self sustaining for all food/supplies,water etc not relying on trade from OTHER countries
the proximity to being invaded..safety, the military, good at protecting the civilization just in case.
the belief system that its unitary..belief in same God,same system of morals etc..not being divided from within from "new ideas" or outside influences..in respect to religions or beliefs.
only with those 4 things can a society last and by lack of any ONE of those 4 things they FALL.
